Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 120MBLS-A-CA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Size / Dimension: T-3 1/4 (physical form factor compatibility)
• Base Type: Bayonet (mechanical interface requirement)
• Color: Amber (optical specification)
• Applications: General Purpose Lighting (functional category)

Voltage Specification: The 120MBLS-A-CA operates at 120V forward voltage. Substitute parts may operate at different voltage ratings (such as 48V) depending on the end-use application and system requirements. Voltage differences indicate the substitute is designed for alternative electrical system configurations rather than direct pin-for-pin replacement in the same circuit.

Compliance & Status: All substitute parts must maintain Active product status and comply with ROHS3 and REACH requirements to ensure regulatory alignment and supply chain continuity.

The identified substitute part 1835LS2-A-CA shares the critical mechanical and optical parameters (T-3 1/4 size, bayonet base, amber color) but operates at 48V, making it suitable for alternative voltage system applications.

Parameter Comparison

Engineering Selection Recommendations

For 120V System Applications: The 120MBLS-A-CA is the specified component for systems operating at 120V with T-3 1/4 bayonet base requirements. This part maintains active production status and full regulatory compliance under ROHS3 and REACH standards.

For 48V System Applications: The 1835LS2-A-CA serves as the equivalent substitute for installations operating at 48V DC. This part shares identical mechanical (bayonet base, T-3 1/4 form factor) and optical (amber color) specifications while accommodating lower voltage system architectures. The 1835LS2-A-CA maintains equivalent compliance certifications and active product status.

Supply Continuity: Both parts are manufactured by the same supplier (VCC) and are currently in stock with substantial inventory levels (696 and 1074 units respectively), supporting reliable procurement for production and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the 1835LS2-A-CA replace the 120MBLS-A-CA in a 120V circuit?

A: No. The 1835LS2-A-CA is rated for 48V operation. Direct substitution in a 120V circuit would result in component failure. Substitution is only valid when the end-use system operates at 48V and requires the same T-3 1/4 bayonet base amber LED lamp.

Q: What are the critical parameters that must match between the main part and substitute?

A: The following parameters must match for valid substitution: Size/Dimension (T-3 1/4), Base Type (Bayonet), Color (Amber), and Applications (General Purpose Lighting). Voltage specifications may differ based on the target system architecture.

Q: Are both parts available in the same packaging format?

A: Yes. Both the 120MBLS-A-CA and 1835LS2-A-CA are supplied in bulk packaging, supporting equivalent procurement and inventory management processes.

Q: Do both substitute parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, ensuring equivalent regulatory alignment for applications requiring these certifications.

Q: What is the primary difference between these two parts?

A: The primary difference is the operating voltage specification. The 120MBLS-A-CA operates at 120V, while the 1835LS2-A-CA operates at 48V. All other mechanical, optical, and compliance parameters are equivalent.
